To all whom z't may concern.'

Be it kno'Wn that I, GEORGE D. HARTLE'LT, a citizen of the United States, residing at Glenbrook, Fairfield county, and State of Connecticut, have invented and discovered certain newl and useful Improvements in Attachments for Gasolene-Engines, of which the following is a specification.

The object of my said invention is to provide an attachment for gasolene engines which may be used for removing the carbon Within the cylinders, and also as a convenient priming device, all as will be hereinafter more'fully described and claimed.

Referring to the accompanying drawings which are made a part hereof and on which similar reference characters indicate similar parts,

Figure 1 is a side elevation of an automobile .engine equipped With my-attachment, F ig. 2 is' a sectional view 'through the controlling valve, and

Eig. 3 a detailed section through the discharge nipple leading into the manifold.

In said drawings the portions marked A represent the intake manifold of the engine, B the radiator, the radiator to the intake manifold.

The engine and radiator are, or may be, of any common or approved construction and need no special description herein.

The pipe C is provided With a valve casing 1'0 at its upper end adjacent to its connection with the radiator, in which is mounted an ordinary three-Way valve 11 provided with an operating handle 12 on its outer end. The casing 10 is formed with a branch 13 adapted to seat in a screw-threaded perforation in the radiator casing and' establish communication from said radiator casing through a port 14 into the valve casing. Another branch 15, with a port 16, is connected with the upper end ofv said pipe C. The lower end of pipe C is appropriately connected to a nipple 1'? which connects at 18, preferably by means of a screw-threaded connection, with aan-aperture in the intake manifold.

and C a pipe leading from The upper end of the valve casing 10 is formed with a cup-shaped receptacle 19, for a purpose to be presently described.

In operation, when it is desired to clean the engine of the accumulated carbon, valve 11 is turned by means of the handle 12, to open communication from the radiator casing into pipe C, which permits Water to pass from said radiator through said pipe through nipple 17 into the intake manifold.. The outlet from said nipple 17 is very small, practically a needle7 opening, which discharges the Water into said manifold drop by drop., As the Water thus drops yinto the manifold it vaporizes forming, a hot vapor Which mixes with the gasolene vapor and passes through the engine, absorbing the carbon and removing it from the iron and permitting it to be blown out at the exhaust.` The' valve 11 is only left open for a short period of time, or a time suiiicient to accomplish the result, usually not more than live minutes.

When it is desired to use the device as a primer, valve 11 is turned to bring the port therein in position to establish communication from cup 19 with port 16, when the priming iiuid can be turned into cup 19 and will pass through pipe C into the manifold and there vaporize and provide the combusti'ble mixture. necessary forstarting the envThe use of this invention affords many ad' valve for controlling communication between said radiator and said manifold 2 v Lesole `forx'nedy with a casing havig a cpshaoed my haifid.l ami sealat-Gienbrook, Connecticut,
